Some lectures are quite fast. If so, the notes may be quite difficult. Please inform with a polite manner. When an uncertain word is received, you can write down at least identified first letters for save time. Then make sure to complete the word as much as possible at the unstructured time. If it is not possible then complete the task after the class definitely.
Once, one student found a solution to speed notes writing problem. It is, taking full responsibility for half of the note correctly at a time, with another student. You can rectify notes completely after the class. This also allows relaxing the pressure on the notes.
Please note that it is needed to find only a person who is dedicated to taking note and who is dedicated to working together.
If you take notes from a classmate, you need to be careful. She may not be the best note taker. You can never get lost after taking notes. Reading other’s lecture notes will increase your understanding of the subject matter and will increase your writing skills.
